Study of Optimal Performance of Taylor Fluid Viscous Dampers under Seismic Prone Zones

Daljeet Pal Singh, Omprakash Netula, Bilal Siddiqui

Abstract


Modern seismic design relies upon the inelastic response of structural members and systems to dissipate the energy imparted to a structure by an earthquake. The approach for controlling seismic damage in buildings and improving their seismic performance is by installing seismic dampers in place of structural elements. These dampers act like the hydraulic shock absorbers in cars and suspension in motorcycles where much of the sudden jerks are absorbed in the hydraulic fluids.

This research aims at a high rise building which is designed and seismic parameters are applied as per IS 1893:2016 Part-1 for different seismic zones on E-Tabs v18 Ultimate as per latest and modified IS Codal provisions. On observation it was found that there is a high maximum storey displacement occurring in the high rise building in vertical direction. Sometimes unknowingly earthquake strikes or fire or due to design error etc. the building collapses and the major structural member column fails which ultimately leads to failure of the structure.

We cannot stop these type of earthquakes and their causing collapses but we can draw some strategies in order to prevent the failure and save lives. So, the structural member column should be so strengthened so that it can resist the various loads like earthquake loads etc. in order to prevent its sudden failure. So, if the column does not fail there will be no sudden collapse of the beam and the mankind will be benefitted.

In order to make our structure safe, the Taylor Fluid Viscous Dampers are designed on the software E-Tabs v18 as per the parameters of Taylor Devices Inc. and then the dampers are applied at some specified locations and finally the most optimum location for the different seismic zones is found which resists the seismic energy and makes the structure safe and secure.

Thus the dampers reduce the energy available for shaking the building and this means that the building deforms less, so the chance of damage is reduced.
